British Airways says it has become the first airline to trial self-service biometric boarding gates on international flights out of the US, working in partnership with Los Angeles Airport (LAX).The airline says: "The new technology, created by Vision-Box, will create a smoother journey for customers, as they will no longer need to present their passport or boarding pass at the gate – only at check in and security. Instead travellers can simply look into a camera prior to boarding, wait for their biometric data to be verified, and then walk onto the aircraft."Similar to facial identification built into mobile phones, the biometric gates use high definition camera technology, and allow customers to pass through by recognising their unique facial features, and reconciling them with the digital facial scan taken as part of the immigration process.British Airways says it has been working closely with the Customs and Border Protection Agency and the US government to develop and approve the scheme.The gates have been installed on three stands at LAX and British Airways is the only airline with the advanced technology to offer purely biometric boarding to its customers.The project, led by LAX, builds on technology already in use by British Airways on its domestic flights from Heathrow's Terminal 5 – checking customers' biometric data at the gate when they scan their boarding pass."Our customers want the ability to simplify and speed up their journeys through the airport, so we're investing in the most advanced technology that will enable us to streamline our boarding process and further improve our punctuality," says Carolina Martinoli, British Airways' director of brand and customer experience. "We're using biometric technology that consumers are now familiar with and trust because it delivers a convenient, reliable and secure experience. This step forward to modernise our operation is a first in the industry, and we will continue to work with airports around the world to evolve this technology, and revolutionise the way in which people travel.""This industry-first deployment of solutions from the US Customs and Border Protection and Vision-Box, shows the amazing potential of using biometrics to speed up the boarding process while maintaining safety and security," says Justin Erbacci, Los Angeles World Airports Chief Innovation and Technology Officer. "We have been very impressed with the results thus far, and love to see the passengers' excitement at being some of the first in the world to use facial recognition to board British Airways flights from LAX to Heathrow."
